A  with one or more .

Notes

• A  is expressed in a human-readable form by its  (FSN).
• A sufficiently defined concept has at least one  that distinguishes it from any  or  that are neither equivalent to, nor subtypes of, the defined concept.

Examples

• The    is sufficiently defined by the following definition because any  for which these defining relationships are true, is either the disorder appendicitis or a subtype of appendicitis.

  74400008|appendicitis (disorder)| === 18526009|disorder of appendix|: 116676008 |associated morphology| = 23583003 |inflammation|, 363698007 |finding site| = 66754008 |appendix structure|

  
  

  
  

  
  

Change Notices

• Prior to July 2018, SNOMED CT could only support one sufficient definition for each  could not represent the  example above. A further limitation, that also prevented formal representation of that example was the stated relationship file was only able to represent .

• Changes introduced in the July 2018 release of the International Edition allow assertions to be represented as axioms in the OWL axiom reference set file. This will allow concepts to be defined by multiple sufficient definitions, some of which may contain assertions that are not necessarily true.
• Following these changes a concept will only be marked as sufficiently defined if it is sufficiently defined by .  However, the OWL axioms may provide a sufficient definition that cannot be fully represented as relationships.

Alternatives

• Fully defined concept
